Django Viewer

Visualize Django project trees, model relationships, URL maps, request flows, middleware, and app summaries from static source.

Developer Input

Django project visualization

Paste Django models, URLs, views, serializers, or multi-file source

# FILE: models.py
class Author(models.Model):
    name = models.CharField(max_length=100)

class Book(models.Model):
    title = models.CharField(max_length=200)
    author = models.ForeignKey(Author, on_delete=models.CASCADE)

# FILE: urls.py
urlpatterns = [
    path("books/", views.book_list, name="book-list"),
]

# FILE: views.py
def book_list(request):
    return render(request, "books/book_list.html")

How to use this developer tool

Paste one or more Django source files.
Select a project, model, URL, request-flow, or summary view.
Set the root URL when mapping endpoints.
Run the viewer and distinguish confirmed, inferred, and unresolved links.

What this developer tool does

The viewer converts parser results into human-readable trees and relationship maps without running Django.

Django parsing → relationship inference → selected tree or flow renderer

Template selection, imported URL modules, dynamic queryset behavior, and indirect dispatch can only be displayed when explicitly present in the supplied source.

Example

A Book ForeignKey to Author is shown as Book.author → Author, while a path connected to book_list and a render call can form a request-flow outline.

Tips for better output

Include models.py, urls.py, and views.py together.
Use literal path and render strings.
Include serializer and router files for DRF maps.
Review unresolved links before relying on the diagram.

FAQ

Does it create a real ER diagram?

It creates a browser-friendly text and relationship map from detected model declarations.

Can it show URL include trees?

It can show literal include and path relationships when the relevant files are supplied.

Does it trace requests at runtime?

No. Request flows are inferred from static source only.

Can it show DRF relationships?

It can detect common serializer, viewset, and router patterns.

Is an external graph library required?

No. The tool uses text and lightweight HTML-compatible output.
